A fictional manned giant robot from the Gundam Mechaverse.
RGM-79 [G] GM Sniper
An Earth Federation modification of the Ground GM MS intended for long range fire support. It is equipped with a larger backpack and loaded a massive beam Sniper Rifle that could only be fired twice, with a long charging time in between shots, without an external power source. Using that external source, however, the GM Sniper could destroy even a cruiser with a single shot.
